Gravity-1 (Yinli-1)

Overview

Solid-propellant medium-lift launch vehicle with a unique configuration of four ground-lit strap-on boosters and three air-lit core stages. Sea-launched from a barge off Haiyang, it is the world's largest and most powerful solid-fuel carrier rocket.

Three successful sea launches to date (January 2024 maiden, October 2025 second, July 2026 third - the first far-sea launch, deploying nine satellites off Shanghai). Orienspace plans three more Gravity-1 batch launches before year-end 2026; hardware for the fourth flight was moved to the Haiyang integration site in early August 2026, targeting a Q3 2026 launch, and had not yet flown as of August 22, 2026.
